wiring harness schematics for a 2012 RT

[onedae]

anyone have access to this. I have not removed the plastic yet but I can see that there are 3 unused connectors taped to the frame. One looks like a 3 wire deal so it is most likely for the GPS. The other 2 are smaller and look like 2 wire connectors. One of the smaller connectors is taped to the bottom of the frame in front of what I think is the GPS connector and the other is taped to the top of the frame in about the same place.

Any ideas??

3-wire power INTO the GPS (and the speed-feed line that increased audio levels)

 

2-wire is audio INTO the radio FROM the GPS

4-wire is the audio OUT from the radio to the "rear speakers"
